Reads a range of 8-bit I2C registers of the specified device sequentially to the given buffer.

This is similar to [[I2C:ReadRegisters8]] except:
* Before selecting the device, this waits 1500ns.
* Before reading the first byte and after reading the last byte, this waits 15µs.

Then reading 4 bytes with starting register 5 would result in:

=Description=
This is identical to [[I2C:WriteRegisters8]].

Writes the given buffer sequentially to a range of 8-bit I2C registers of the specified device.

For example, writing a buffer of consisting of <code>{ 0xAA, 0xBB, 0xCC, 0xDD }</code> with starting register 0x5 would do the following:

<pre>
reg[0x5] = 0xAA
reg[0x6] = 0xBB
reg[0x7] = 0xCC
reg[0x8] = 0xDD
</pre>

=Description=
Reads a range of 8-bit I2C registers of the specified device sequentially to the given buffer.

For example, assuming:

<pre>
reg[5] = 0xAA, reg[6] = 0xBB, reg[7] = 0xCC, reg[8] = 0xDD
</pre>

Then reading 4 bytes with starting register 5 would result in:

<pre>
outbuf[0] = 0xAA
outbuf[1] = 0xBB
outbuf[2] = 0xCC
outbuf[3] = 0xDD
</pre>

This is similar to [[I2C:WriteRegisters8]] except this uses 16-bit registers.
